5.MAIN POWER CONNECTION.
Confirm that the label next to the connected outlet on the machine
matches your power supply. Connect one end of the main cable to a
connection socket and the other end to a grounding socket. Under no
circumstances should you turn on the device if the voltage does not
correspond.
Fluctuations along the line should be less than 10%. If this value is
exceeded, the fuse will blow. They are located in the connecting socket
and are externally accessible. Again, do not connect this device to a
standard extension cord or power strip. Connect it directly to a grounding
outlet or use a surge protective device rated over 2000J.
6.WATER-COOLED INSTALLATION.
The supplied water pump is critical to the performance and service life of
the engraving machine. When such a laser works without a properly
maintained cooling system, its glass tube can explode due to
overheating.
Never touch or adjust the water supply of the engraving machine while
the pump is plugged in.
To use the water pump, fill a dedicated tank with at least 2 gallons (7.5
liters) of distilled or purified water This will gradually reduce the quality of
the engraving machine and may even lead to dangerous mineral
accumulation.Cooling system. For the same reason, never use
all-purpose antifreeze. Use custom laser-safe formulations or storage
Engraving machines in climate-controlled areas.
Note：Distilled water or purified water must be added, not tap water
or sewage, otherwise it will reduce the service life of the
product.
